Application filed March 18, 1924. Serial No. 699,993.

To all 'LU/LOWZ it may concern:

. Be itknown that I, PERCY L. Snsonn, a citizen of the United States, and resident of Newark, in'the county of Essex and State of Newdersey, have invented certain new 1 pile of sheets together with means for operating said nozzle to convey the separated sheet to the platen of the press, which is shown as aChandler & Price job press.

Thesuction nozzle is carried by an arm 2 secured to and movable with the form memberof the press and also to the connecting rod which operates the form member. a

" The object of this inventionis to generally improve the supporting means for the 2 suction nozzle, and the means for attaching it to the press, whereby to provide for necessary adjustments, both during the mounting or attachingof the mechanism to the; press,

as well as providing for adjustments which 1 may be required from time to time because of wear or for other reasons.

the invention en'lbodied in a suctionnozzle sirpporting mechanism arran god and constructed as hereinafter set forth and as illus trated in the accompanying draw nguu which- Flgure 1 1s a view of my improvednozzle supporting mechanism attached to' a" press,

- 4oflwith parts omitted and parts broken away.

Figure 2 is a detail view in side elevation of certain parts of the said mechanism.

Figure?) is a view partly in sectionof the parts of said mechanism which are directly attached to the press.

Only so much of the press is illustrated as is necessary to an understanding of th s 111- press and the paper separating and feeding mechanism, as well as the construction and operation of the nozzle, reference is made to the U. S. patent aforesaid.

The frame of the press is marked 1 and a secured to the is separated fromthe pile 11 by a suction nozzle 14 mounted on a rod 15. The nozzle 1th the above and other objects in view, 1

the oscillatingplaten is represented at 2 and is pivoted in the frame at 3. a The form member 4 is the usual Chandler & Price form member which is operated by connecting rods, one of which is shown at 5 pivoted at 6 to the gear 7 on the press. The gear is.

shown in outline only so as not to interfere with the other parts of the press which are located behind said gear.

Referring to Figures 2 and 3, the numeral 8 denotes the form member shaft to which the form member is attached as shown by a portion of the member 4. The member 9 represents the usual swinging ink frame. The form member shaft carries the usual eecentric stud 10 on which the one end of the connecting rod 5 is journaled. 1

.All of the foregoing parts are standard V on this type of press and require no further description. 1 i

As set forth in the patent referred to the paper 11 is supported on an inclined sup port 12 which rests on a suitable bracket 13 press. The top sheet of paper picks up the top sheet and carries it to the platen, either directly or delivers the sheet to intervening feed tapes or like means as set forth in the said patent.

The rod 15 is secured to a nozzle head 16 by a set screw 17. The nozzle head also carriesa roller 18 which runs on a cam 19 for the purpose of guiding the movement of the nozzle head and suction nozzle. The nozzle head is further provided with an integral clamping member indicated at 20 by means of which the head is carried by a nozzle arm 21 being secured by a bolt 22.

The nozzle arm is operated tomove with the press so as to properly move and guide the suction nozzle. To this end there is secured to the press a. nozzle arm support to whichis pivoted a nozzle arm bracket which carries the nozzle arm. 1 r

The nozzle arm support is in the form of I a casting 23 provided with two lugs 24, 24 vention. F or a detailed disclosure of the in alinement with the connecting rod 5. Adjusting bolts 25, 25 pass through the lugs 24 and engage the connecting rod to firmly clampthe support 23 to said rod 5. The support further comprises a second larger casting 26 secured to the casting 23 by bolts 28. In order to axially align the two castings 23 and 26, an eccentric ring 29 is fitted over the end of the shaft 8 and the casting 26 is provided with a hub 30 which is clamped on said eccentric ring 29 by a bolt 31.

Finally, the support 23 is secured to the form member shaft 8 by a stud 32 which passes through the support 23, and engages in a hole 33 which is normally to be found in the end of the shaft 8 on the press itself. The support 26 carries a stop 3 1.

The upper end of the, support 26 carries a bolt 35 bymeans of which the nozzle arm bracket 36 is pivoted to the support. The bracket 36 is pivoted with lugs 37,- 37 adapted to receive the rear end ofthe nozzle arm 21. A pivot bolt 38 passes through the lugs 37 and the nozzle, arm'21 and adjusting screws 39 engage the latter and keeps it in proper position with respect to the bracket 36. which carries a stop 11.

The parts are so arranged and proportioned that the nozzle head 16 rests on the cam 19 by gravity during the operation of the device. As the pressopens, the roller 18 rides up over the cam thereby lifting the suction nozzle with the top sheet upwards away from the pile, and through the further continued movement of the form member (to the right in Figure 1) the separated sheet is taken away from the pile and at the proper time dropped from the nozzle.

When the press closes the nozzle head with nozzle is jagain moved into the position shown in Figure 1.

During the operation of the press, the nozzle arm supports 23 and 26 remain fixed in their relationship to the connecting rod 5, While of course the nozzle arm bracket swing on the bolt 35 as will be understood.

The invention presents several advantages of particular importance when the device is attached to the press. It is appreciated by persons skilled in the art that great care is required to properly adjust and position the suction nozzle with respect to the paper, because if the nozzle is not accurately squared and adjusted, the paper cannot be properly placed on the platen or what ever paper feeding means may be employed between the nozzle and the platen. The main object of the invention is to provide means for properly positioning the nozzle and its operating parts.

, When the device is attached to the press, it will be seen, that the supports 23 and 26 may be accurately adjusted in a vertical plane around the stud 32 and on the form member shaft 8 by means of the adjusting and clamping bolts which firmly clamp the support to the connecting rod 5. The stud 32 prevents endwise movement of the supports on the shaft 8 and the eccentric ring 29 accurately aligns the support 26 with the support 23. In addition the said eccentric ring 29 provides a firm foundation for the clamping of the hub 30 of the support 26' to the shaft 8 without interfering with the normal free movement of said shaft.

The arm 21 is thus adjusted vertically in that its rear end (to the right in Figure 1) is raised or lowered depending upon the adjustment of the supports 23 and 26 as aforesaid.

Again, the nozzle arm is adjustable laterally on the pivot bolt 38 and finally secured by the screws The nozzle head 16 is adjustable lengthwise of the nozzle arm 21, said head having a recess 40 permitting such adjustment, and the nozzle head is likewise adjustableaxially on the nozzle arm and is finally clamped firmly by the means of the bolt 22.

Thus all possible and required adjustability of the device has been provided for to insure quick installation by the simple turning of a few screws. The device is accessible and may be easily inspected and adjusted from time to time besides presenting a neat appearance.

When making ready or for other reasons, the nozzle head and nozzle arm may be swung upwards out of the way as is indicated in dotted lines in Figure 1, in which position the stop 36 abuts and rests against the stop 30.
